CONDENSER FOR STEAM-PUMPS.

SPECIFICATION forming part of Letters Patent No. 272,457, dated February 20, 1883.

Application filed December26,1882. (No model.) I

To all whom it may concern Be it known that I, WILLIAM A. MILEs, of Gopake Iron Works, in the county of Columhia and State of New York, have invented an Improvementin Condensers for Steam-Pumps,

densation and in freeing the condenser from atmosphere. My present invention is made for overcoming this difficulty.

In the drawing I have represented the improvement by a sectional View. 7

The water is drawn from its supply through the pipes at b c to the pump in the direction of the arrow. The pipe!) is sufficiently enlarged to receive the condenservessel d within it without obstructing the suction water-way. This vesseld is preferably along tube with its ends closed and theexhaust-steam pipe 6 passing into its upper end. The object of this is to cause the steam to displace the air by accumulating in the upper part of the vessel d and driving down the air, which is heaviest; and in order to draw off this air, and also to remove the water of condensation, I make use of the pipe Z, passing from the bottom of the vessel 01 and opening in the direction in which the water is flowing through the suction water-way, so that the vacuum action of the pump may free the condenser from air and from the water of condensation. It is preferable to place a check-valve, s; at the bottom of the pipel to prevent water being drawn into the vesseld when the vacuum therein is greater than that in the suction-pipe.

Itis advantageous to introduce the condens-- o er-ve's'sel as high as possible in the suction water-way to obtain the vacuum action due to the column of water, and I remark that a siphon may be employed in cases where the water is drawn up but a small distance by the pump. This feature,however, is set forth in other applications of mine heretofore made.

I remark thatif it is desirable to provide easy access to the check-valve it may be placed outside the pipe I), and the pipe he led out from the vessel 61 to such check-valve, and then back again into the water-way, as represented by dotted lines.

I claim as my invention-- 1. In a condensing apparatus for steampumps, the combination, with the water-way pipes, ofacondcnsing-vessel within the waterway, an exhaust-steampipe opening intothetop part of the condensing-vessel, and a pipe from the lower part of the condensing-vessel opening into the suction water-way, substantially as set forth.

2 In a condensing apparatus for steampumps, the combination, with the water-way pipes, of a condensing vessel within the water-way, an exhaust-steam pipe opening into the top part of the condensing-vessel, a pipe from the lower part of the condensing-vessel opening into the water-way, and a check-valve, substantially as set forth. 7o
